Question

Suppose that Alice wants to send Bob a 50 kilobyte message over a 1 Gbps link. The total time required to transmit the message (i.e., message latency) is 2 milliseconds. What is the throughput of the connection? Express your answer in Mbps rounded to the nearest whole number, and leave off the units. For example if the answer is 857.7823 Mbps, fill your answer in as 858

Answer 1

170 Mbps

Step-by-step explanation:

Time taken to put data on to the link T1 = 50kB / 1 Gbps = 0.0004096

Time taken for transmission T2 = 2 milliseconds = 2 * 10-3

--> throughput = ( 1 / (1+T2/T1) ) * bandwidth of link

= ( 1 / (1 + 4.8828125) ) * 1 Gbps

= 0.16998672 * 1 Gbps

= 169.98672 Mbps

= 170 Mbps.
